Number World’s Farms To Halve By 2100

“The size of the farm and the number of farms that exist are associated with key environmental and social outcomes.”

Editors note from a source from who works (full time) to help small sustainable farms stay sustainable and plan for continuing adaptation to climate change:

“This article summarizes a trend in agriculture (based on a peer reviewed study) which I think is not a surprise to most of us. Farms are going to continue to be consolidated into larger operations owned and operated by fewer people in the future. This trend is not good news for humans or the planet overall. (Except, likely, for the corporations that own more and more valuable land.)

“It confirms the need for increased biodiversity of small farms, improving access and food security, and continuation of valuable indigenous agricultural knowledge.”

The number of farms in the world is declining. Here’s why it matters to you.

A new University of Colorado-Boulder research shows that the number of farms globally will shrink in half as the size of the average existing farms doubles by the end of the 21st century, posing significant risks to the world’s food systems.

Published in the journal Nature Sustainability, the study is the first to track the number and size of farms year-over-year from the 1960s and projected through 2100.

The study shows that even rural, farm-dependent communities in Africa and Asia will experience a drop in the number of operating farms.

Zia Mehrabi, Assistant Professor

“We see a turning point from widespread farm creation to widespread consolidation on a global level, and that’s the future trajectory that humanity is currently on,” said Zia Mehrabi, assistant professor of environmental studies at CU Boulder. “The size of the farm and the number of farms that exist are associated with key environmental and social outcomes.”

To evaluate the global state of farming, Mehrabi used data from the UN Food and Agricultural Organization on agricultural area, GDP per capita, and rural population size of more than 180 countries to reconstruct the evolution of farm numbers from 1969-2013 and then project those numbers through 2100.

His analysis found that the number of farms worldwide would drop from 616 million in 2020 to 272 million in 2100. A key reason: As a country’s economy grows, more people migrate to urban areas, leaving fewer people in rural areas to tend the land.

Reap what you sow

A decline in the number of farms and an increase in farm size has been happening in the United States and Western Europe for decades. The most recent data from the U.S. Department of Agriculture indicates 200,000 fewer farms in 2022 than in 2007.

Mehrabi’s analysis found that a turning point from farm creation to widespread consolidation will occur as early as 2050 in communities across Asia, the Middle East, North Africa, Oceania, Latin America, and the Caribbean. The research found that Sub-Saharan Africa will follow the same course later in the century.

It also shows that even if the total amount of farmland doesn’t change across the globe in the coming years, fewer people will own and farm what available land. The trend could threaten biodiversity when biodiversity conservation is top of mind.

“Larger farms typically have less biodiversity and more monocultures,” Mehrabi said. “Smaller farms typically have more biodiversity and crop diversity, which makes them more resilient to pest outbreaks and climate shocks.”

And it’s not just biodiversity: Food supply is also at risk. Mehrabi’s previous research shows the world’s smallest farms make up just 25 percent of the world’s agricultural land but harvest one-third of the world’s food.

Moreover, fewer farms mean fewer farmers who may carry with them valuable Indigenous knowledge dating back centuries. As farms consolidate, that knowledge is replaced by new technology and mechanization.

Building a diverse food portfolio

Just as a diverse investment portfolio performs better than one that is not diversified, having diversity in the world’s food source portfolio is beneficial in the long run, said Mehrabi.

“If you’re investing in today’s food systems with around 600 million farms in the world, your portfolio is pretty diverse,” Mehrabi said. “If there’s damage to one farm, it’s likely the impact to your portfolio will be averaged out with the success of another. But if you decrease the number of farms and increase their size, the effect of that shock on your portfolio will increase. You’re carrying more risk.”

There are also upsides to the shift in corporate farm ownership: The paper points out that consolidation in farming can lead to improved labor productivity and economic growth with a larger workforce in non-farm employment and improved management systems.

One of the most significant benefits of farm consolidation, Mehrabi said, is improved economic opportunity for people and the ability to choose their career path within our outside of the agricultural sector.

But those future farm workers may need more support as suicide rates in the agriculture industry are among the highest rates by occupation in the U.S.

“Currently, we have around 600 million farms feeding the world, and they’re carrying 8 billion people on their shoulders,” Mehrabi said. “By the end of the century, we’ll likely have half the number of farmers feeding even more people. We need to think about how we can have the education and support systems in place to support those farmers.”

By raising awareness of global agricultural trends, Mehrabi hopes his analysis will lead to policies that ensure biodiversity conservation, maintain climate resilience, preserve Indigenous knowledge, and provide incentives to improve the rural economy in countries worldwide.

Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours.
